A bevel gear 22 arranged in an end part of the rotor shaft 3 facing in a beval gear chamber is meshed so as to interlock with a beval gear 23 on the crankshaft 8 through beval gears 24, 25 to perform four strokes by single rotation of the crankshaft 8 and the rotor 1 to generate motive power.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary piston engine device which forms a compression mechanism and which is a combination of a reciprocating type and a rotary type.

[0002]

2. Description of the Related Art In automobiles, remarkable progress has been made by high-tech technology, but the basic structure of the engine itself remains unchanged. Therefore, in the conventional reciprocating engine, the structure of the gas exchange between the intake and exhaust is a valve mechanism, so the size, position, number, and heat of the valve. Alternatively, the biggest disadvantage is that gas exchange is significantly impaired because the operation is restricted by the timing of operation. The disadvantages are as follows. , The structure is complicated and expensive. In addition, intake and exhaust are hindered by the restriction of the valve mechanism, resulting in energy loss. ,
There is an overlap in the opening and closing timing of the valve, resulting in energy loss due to airtightness. As a result, the collection of multi-cylinder exhaust pipes causes energy loss due to exhaust interference.
, Wankel and rotary engines are said to be lightweight, compact and have a high output, which is advantageous for the practicality of hydrogen engines.However, there is overlap in intake and exhaust, energy loss due to airtightness, poor fuel economy, low speed torque. It is considered weak.

[0003]

With the increase in the production and the size of automobiles, natural destruction and global warming due to pollution by exhaust gas, especially carbon dioxide, are progressing, and development of low-emission vehicles has become a global urgent issue. . Countermeasures are being taken by stakeholders, and new low-emission vehicles such as battery cars, solar cars, and hydrogen engine cars have been developed. However, there is a problem in price and practicality, and there is currently no significant effect.

[0004] In order to solve the above problems, the present invention provides a simple mechanism and eliminates all the overlaps with valves for intake and exhaust, etc., thereby forming independent processes. The purpose of this device is to develop a new low-emission vehicle engine by making it easier to control the temperature suitable for the vehicle.

In order to achieve the above object, hollow rotary shafts 2, 3 are fixed to the rotor A,
Arbitrary number of cylinders 4 and 5 (here, two cylinders) are provided, pistons 6 and 7 are provided in the cylinder, hollow rotary shaft 8 is provided through the crankshaft, and cranks 9 and 1 are provided.
0, and are connected so as to be rotatable in con-lots, 11 and 12. A housing 13 is provided with a rotation bearing hole, and a suction hole 14, a suction auxiliary hole 15, spark plugs 16 and 17,
Exhaust hole 18, exhaust auxiliary hole 19, bevel gear receiving shaft 20,
21 to rotatably enclose the rotor and the bevel gear.

A, the rotor is a perfect circle and a cylindrical shape, and has hollow rotor shafts 2 and 3 and rotates about the rotor shaft. With the rotation axis as the center, the two cylinders 4 and 5 are arranged around the rotor at 0 degree (and 360 degrees) on the OP line as shown in FIG. (Here, two), this position is used as the starting point of the suction process and the explosion process. The position Q on the QR line is 90 degrees and the R position is 270 degrees, which is the starting point of the counterclockwise compression process and the exhaust process. A hollow rotor shaft is provided with a crankshaft 8 and cranks 9 and 10 are provided with conlots 11 and 12 and pistons 6 and 7 and are rotatably assembled to cylinders 4 and 5 to bevel gears 22 on the rotor shaft and a crankshaft on the rotor shaft. The bevel gear 23 is fixedly provided.

[0007] B, the housing 13 is a mother body that encloses the rotor, has a rotary bearing hole in the center, and has a suction hole 14, a suction auxiliary hole 15 based on the starting point of each process as a mechanism of gas flow in each process. , Ignition plugs 16, 17, exhaust holes 18, exhaust auxiliary holes 19, bevel gear receiving shafts 20, 21,
It has a bevel gear chamber on the side and encloses the rotor and bevel gear.

C, the four bevel gears are provided with a bevel gear 22 fixed to a rotor shaft of a bevel gear chamber and a bevel gear 23 fixed to a crankshaft. At the upper arrow 0 degree, the rotor cylinder 4,
And the pistons of the crank 9 are engaged with each other under the condition that the pistons are at 0 degrees.

D, side housings 26 and 27, which are a base body surrounding the rotor and the bevel gear from the side, have a rotor bearing hole and a crank bearing hole.

[0010] The rotor of E and A and the bevel gear of C
And the side housing of D are rotatably assembled, and the ratio of the number of meshing teeth of the bevel gear is 1: 1.
Thus, the rotor shaft forms a left rotation and the crankshaft forms a right rotation.

Since the rotor shaft and the crankshaft rotate in reverse, one rotation of the rotor shaft and one rotation of the crankshaft form four steps and four strokes, and the suction, compression, explosion, and exhaust steps are completed. Two explosion energies are generated by forming a process and performing continuous rotational movement.

With the structure as described above, with the rotation axis as the center,
Turn the crankshaft clockwise with an external force in the direction of the arrow, and check the gas flow, each process and the stroke of the crankshaft. The upper part on the housing OP line is 0 degree (and 360 degree).
As the starting point of the suction process, when the crank shaft is turned clockwise in the direction of the arrow at the point 0 at the center point of the cylinder 4 of the rotor shaft and the crank 9 at the top dead center and the crank 9 at the top dead center, the cylinder rotates counterclockwise. Begins, and when the air continues to rotate a little, the air-fuel mixture flows from the suction hole through the suction auxiliary hole, and the rotor is Q
At the point, the crank 9 finishes the suction process and the suction stroke at the point R,

At the same time, the cylinder 5 is acted upon by the ignition plug at the point 180 degrees P below, and the cylinder 10
Moving from point to point Q to the exhaust stroke from the explosion stroke, the explosive gas is discharged from the exhaust auxiliary hole and the exhaust hole.

Further, the cylinder 4 is operated in an explosion process 180
The ignition plug 14 at the point P receives the explosion energy and rotates to discharge the explosive gas from the exhaust auxiliary hole and the exhaust hole. The crank 9 has passed the point Q and is approaching the exhaust completion point of 360 degrees.

At the same time, the cylinder 5 is set to 0
Exceeding the degree, it is heading to the compression process while sucking the gas mixture through the suction auxiliary hole from the suction hole. Crank 10 is 0
Passing the point, it is heading to the opposition position R point. When the ignition plug 15 proceeds further, the ignition plug 15 causes an explosion.

Further, the second rotation, cylinder 4 is 36
Simultaneously with the completion of the 0-degree exhaust process, the mixed gas is sucked from the 0-degree intake hole through the suction assisting hole, and the process proceeds to the compression process.
The crank 9 has passed the zero point and is heading to the opposing position at the R point of 270 degrees. If you proceed further, it ignites and explodes with spark plug 14 and 2
A rotary piston engine device that generates energy every 180 degrees in a cylinder.

[0017]

Since the present invention is configured as described above, it has the following effects.
A: A simple structure, lightweight, compact, high torque and high horsepower can be obtained. Because there is no intake and exhaust valves, there is no restriction or obstruction of the exchange gas, so there is little energy loss, and there are few torque fluctuations because there are four steps per crank rotation.
